The Beckhoff FB1111-0141 is an EtherCAT piggyback controller board designed for integration into industrial automation hardware and evaluation environments. This variant of the FB1111 series provides a Serial Peripheral Interface (SPI) slave Process Data Interface, enabling communication between external control electronics and the onboard EtherCAT Slave Controller.
Built around the Beckhoff ET1100 EtherCAT Slave Controller, the FB1111-0141 combines two EtherCAT ports, integrated PHY components, RJ45 connectivity, EEPROM, status indication LEDs and a 52-pin PDI connector on a compact printed circuit board. The board includes indicators for 5 V power, RUN status, and Link/Act activity for both EtherCAT ports, helping make device state and network activity easy to identify during integration.
The FB1111-0141 operates from a 5 V board supply and provides a 3.3 V output with limited available current for connected circuitry. Its inputs and outputs are 3.3 V compatible, making correct voltage matching important when pairing the board with host electronics. Typical operating conditions include an ambient temperature range of -40 °C to +70 °C, making it suitable for demanding automation development and embedded industrial designs.
This Beckhoff piggyback controller board is particularly suited to applications where EtherCAT connectivity needs to be added to custom electronics using an SPI-based interface. It is commonly associated with EtherCAT evaluation, prototyping, machine control development and integration into third-party industrial devices requiring real-time Ethernet communication capability.

What does this piggyback controller board do?
It is an EtherCAT piggyback controller board designed to add EtherCAT slave communication to an embedded or automation device. The FB1111-0141 combines an ET1100 EtherCAT Slave Controller, two EtherCAT ports and a Process Data Interface connector on one compact PCB.
Which Process Data Interface is used on this board?
This variant uses an SPI Process Data Interface. In the FB1111-014X series, the 0141 sub-code identifies the Serial Peripheral Interface slave version.
How many EtherCAT ports are fitted?
The board has two EtherCAT ports. Each port includes a PHY, magnetics and an RJ45 connector, allowing it to be integrated into an EtherCAT line topology.
What supply voltage does the board require?
The board is designed for a 5 V DC supply. The typical board supply voltage is 5.0 V, with a stated operating range of 4.0 V to 5.5 V.
Does the board provide a 3.3 V output?
Yes. Pin 50 on the PDI connector provides a 3.3 V output from an onboard DC-DC converter. The maximum current from this output is limited to 100 mA.
Are the input and output signals 5 V tolerant?
No. The I/O signals are 3.3 V compatible. Applying higher voltages to the inputs or outputs can damage the board.
Which status LEDs are included?
The board includes four indicator LEDs: +5V for supply indication, RUN for application state, Link 0 for port 0 link/activity and Link 1 for port 1 link/activity.
What is the operating temperature range?
The stated ambient temperature range is -40 °C to 70 °C. The stated storage temperature range is -65 °C to 105 °C.
Can the PDI configuration be modified?
The FB1111-014X family uses alternative resistor placements to create different PDI connector pinouts. However, incorrect resistor configuration can cause serious board damage, so changes should only be carried out by qualified automation or electronics personnel.
Can this SPI version be directly replaced by the digital I/O version?
No. The SPI, microcontroller and 32-bit digital I/O variants use different PDI connector pinouts. A programmed digital I/O variant should not be assumed to be a direct physical replacement for the SPI version.
What connector arrangement is used for the PDI connection?
The board uses a board-to-board connector identified as CON500. The connector can be mated from the top or bottom side, with a low-profile socket equivalent to Samtec CLH-126-F-D-BE-P-TR referenced in the hardware data.
What mounting consideration is important for EMC performance?
For electrostatic discharge protection, the top-left mounting hole should be connected to a substantial panel or plate tied to GND-Earth. The remaining mounting holes are intended for mechanical fixing.
